Bluetooth + USB logger

B3 Read it without pulling the logger.

Don't open the carton to know if the trip was clean. The Cydiance App downloads over Bluetooth — bag on. At destination, the same device still writes PDF and CSV on USB. Silent Records if the start is missed, down to −30°C.

Cydiance B3 Bluetooth USB temperature logger — B3 · USB Type-A + BLE · 94 × 50 × 6 mm

Why B3

Leave it in the bag

Scan at the dock. Charts and summaries come down over Bluetooth — no USB, no tearing the food-grade bag, no fishing the logger out of the carton.

USB is still there

When the buyer wants a file, plug in. PDF and CSV write on board in about 14 seconds, no software install. Bluetooth is extra recovery, not a replacement for the stick.

The record that comes back

Start from the button or the App. If someone forgets, Silent Records keeps a factory backup CSV. The trip does not wait for a PC to show up.
